From Zoomies To Side-Eyes: A Dog Expert Explains 17 Curious Canine Habits

Because they miss them and they didn’t know how long they would be gone for.

Dogs don't experience time quite the way humans do, so every reunion feels exciting, regardless of how long you've been away.

Many dogs develop strong attachments to specific toys because they provide comfort, familiarity, and security, much like a child's favorite blanket.

Your dog doesn't understand privacy. They understand companionship. If you're moving, they assume something important is happening and they'd better supervise.

Leaves, tissues, cardboard, mysterious objects from the garden — no, your dog isn't confused. They're often trying to share something they find interesting or valuable.

It may feel awkward, but the dog isn't judging the owner. In the wild, bathroom breaks leave animals vulnerable, so many dogs instinctively look to a trusted human to stand guard. To dogs, pooping isn't some special private thing, so there’s no reason not to look at their beloved human.

Often, "nothing" means a distant sound, unfamiliar scent, or movement far beyond human perception. Dogs experience the world through senses much sharper than ours.

That spot is warm, smells like human, and has already been approved by the most trusted person in the house. From a dog's perspective, it's prime real estate.

The head tilt may help dogs pinpoint sounds more accurately, but many researchers believe it's also linked to concentration and curiosity.

Some dogs seem determined to prove that bigger is always better. Carrying oversized objects may stem from natural retrieving instincts, or simply because it makes them feel accomplished.

Dogs evolved in environments where food wasn't guaranteed. Modern dogs may have full bowls and still enthusiastically audition for the role of "starving orphan."

Also, some dog breeds seem to have been bred to have more hunger than they need.

The famous "guilty look" is less about guilt and more about reading your body language. Dogs are experts at detecting when humans are unhappy.

To humans, it's disgusting. To dogs, it's fascinating. Some scientists believe this behavior may be linked to ancient instincts involving scent masking and communication.

Contrary to popular belief, they're not covering it up. They're actually advertising it. Dogs have scent glands in their paws, and by scratching the ground, they spread their scent and leave a visible mark behind. In other words, they're not hiding their presence, they're advertising it.

That theatrical sigh isn't necessarily a sign of exhaustion from a hard day at the office. Most experts believe it's simply a way for dogs to release tension and settle comfortably.

Known as "zoomies," these sudden bursts of energy are perfectly normal.

It means dogs aren’t getting enough opportunities to burn off their energy.

To humans, rain is just weather. To dogs, it can completely transform how the world feels. Rain weakens many of the scent trails dogs use to navigate their surroundings, while the sound of falling water and the sensation of droplets hitting their fur can be unpleasant or even stressful. Some dogs are particularly sensitive to changes in texture and temperature, making wet conditions less enjoyable. Scientists believe these factors, combined with individual personality and past experiences, help explain why some dogs charge through storms while others plant their paws firmly on the doorstep and refuse to negotiate.

Poop is high in protein and some dogs are much less fussy about what things taste like than we are.
